To create a shader in SwiftUI, you can instantiate it by calling a function with its name from the shader library. You can pass additional parameters to your shader function, such as colors, numbers, or an image. When you apply this effect to a view using the layer effect view modifier, SwiftUI will call your shader function for every pixel of your view. Shaders are written in the Metal shading language and run on the device's GPU, which is optimized for highly parallel tasks.
